Key Features

• Core: RC32300 MIPS‑II CPU core, single 32‑bit core supporting up to 150 MHz operation and both big and little endian modes.
• Cache & MMU: 8 kB instruction cache (2‑way, lockable) and 2 kB data cache (2‑way, lockable); MMU with a 32‑entry page TLB and cache control options for write‑back/write‑through policies.
• Memory Controllers: Integrated SDRAM controller supporting 4 non‑interleaved banks and up to 512 MB total SDRAM; memory & peripheral controller with 6 banks supporting 8‑, 16‑ and 32‑bit interfaces for Flash, SRAM and other devices.
• DMA: Four general‑purpose DMA channels with support for scatter/gather, chaining, endian swapping and unaligned transfers; programmable burst sizes up to 16 bytes.
• Bus & PCI: Local bus interface (up to 75 MHz, 26‑bit address, 32‑bit data) and 32‑bit PCI interface (up to 66 MHz, PCI rev. 2.2 compatible) supporting target and master roles.
• Peripherals & Serial Interfaces: Two 16550‑compatible UARTs (baud support to 1.5 Mb/s), SPI master, programmable I/O (PIO) and four 32‑bit timer/counters for system control and serial communications.
• System & Debug: Interrupt controller, EJTAG in‑circuit emulator interface and IEEE‑1149.1 JTAG support for debug and test.
• Package & Power: 256‑ball PBGA (17 × 17 mm, 1.0 mm ball spacing), surface mount; 3.3 V operation with 5 V tolerant I/O.
• Environmental & Qualification: Consumer qualification and RoHS compliant; operating temperature range 0 °C to 70 °C.

Typical Applications

• Embedded Communications: Integration of CPU, DMA, PCI and serial interfaces makes this device suitable for embedded communications controllers and networking endpoints.
• Consumer Embedded Devices: Consumer‑grade embedded systems that require a single 32‑bit core, on‑chip memory controllers and UART/SPI connectivity.
• Board‑Level System Control: Local bus and peripheral controller features enable direct control of memory and onboard peripherals for compact system designs.

Unique Advantages

• Integrated Memory Subsystem: On‑chip SDRAM controller and multi‑bank memory/peripheral controller reduce external memory interface complexity and BOM.
• Flexible DMA and Bus Options: Four DMA channels with scatter/gather and PCI/local bus support streamline high‑throughput data movement without CPU intervention.
• Deterministic Cache Control: Lockable instruction and data caches plus programmable cache algorithms provide control over memory behavior for latency‑sensitive embedded tasks.
• Comprehensive Peripheral Set: UARTs, SPI, timers, PIO and PCI connectivity provide versatile I/O options for varied embedded system requirements.
• Debug and Development Support: EJTAG and JTAG interfaces along with documented processor features support hardware debug and development workflows.
• Compact, Industry‑Standard Package: 256‑ball PBGA (17×17 mm) enables a compact board footprint with surface‑mount assembly.
